Guide Highlights • Comprehensive state-of-the-art-review on the seismic response of Integral Abutment Bridges (IABs). • Challenges in earthquake-resistant IABs are discussed with the view of
Guide Integral abutment bridges (IAB) consist of a continuous concrete deck integrated with abutments generally supported by a row of piles and they are cost-effective with less maintenance
Guide The type of abutment selected depends largely on the span of the bridge and its seismic vulnerability. In this article, we will explore these two types of abutments, the seismic vulnerabilities
Guide Thus it is now possible to evaluate the seismic vulnerability of existing abutments. The theory also relates directly to design recommendations to increase the seismic capacity of both
Guide Abutment behavior significantly influences the seismic response of certain bridge structures. Specifically in the case of short bridges with relatively stiff superstructures typical of
Guide This study develops a reliability-based optimization methodology for bridge abutments under seismic conditions. Key failure modes include sliding,

Guide The seismic performance of integral abutment bridges (IABs) is affected by the interaction with the surrounding soil, and specifically by the
Guide 11.1.2 TYPES OF ABUTMENTS The most common types of abutments used for highway bridges are shown in Figure 11.1.2-1. In general, abutments can be classified as open-end and closed-end. The
Guide Equally, there is a notable lack of numerical studies of IABs focusing on seismic earth pressures validated by experimental data. A recent work by Fiorentino et al. 47 reported on the
Guide This approach is implemented in OpenSees and is validated against the results of a fully coupled soil-bridge finite-element model subjected to seismic loading. Finally, a seismic design procedure for
Guide A comprehensive model addressing both the dynamic compliance of the soil-foundation system and the foundation input motion is recommended for reliable seismic assessment of bridge
Guide To this purpose, the present paper describes a design technique in which the frequency- and amplitude-dependency of the soil-structure interaction
Guide This paper focuses on the seismic performance and design of a single-span integral abutment bridge (IAB), as a structural system characterised
Guide SUMMARY: Abutments are not only earth-retaining systems, but also contribute to the earthquake resisting system (ERS) of bridges. The backfill-abutment-bridge interaction has been extensively
Guide This comprehensive analysis underscores the importance of incorporating advanced bracing systems in bridge substructures to mitigate seismic impacts, offering insights for future
Guide This work regards the analysis of the seismic response of bridges isolated with single concave friction pendulum devices, including or neglecting the presence of the rigid abutment. Two
Guide Significant research progress has been made on the seismic design of steel bridges, including shear links, buckling-restrained braces, ductile end cross frames, and integral bent cap connections.
Guide The paper proposes a methodology for assessing the seismic soil-foundation-abutment response in the spirit of the sub-structure approach. The methodology is suitable for conventional
Guide This study investigates the effects of the soil-abutment interaction on seismic analysis and design of integral bridges. Past experience and recent research indicates that soil-structure interaction plays a
Guide An essential component of the economics of the entire bridge project is choosing the right kind of abutment given the site characteristics. This study involves the seismic analysis and
Guide This paper investigates these limitations and evaluates the AASHTO code recommendations regarding the prediction of the seismic responses of curved bridges using an equivalent straight bridge for
Guide This paper investigates the effect of abutment stoppers on the seismic response of motorway bridges in the longitudinal direction. A rigorous 3D finite element model of a representative
Guide Therefore, this study aims to investigate the nonlinear behavior and seismic capacity of the fully integral bridge and then to assess the appropriate stiffness of the end-restraining abutment
Guide For assessment of seismic damages in bridges, damage states need to be established for the components. Although, past studies have focussed on the possible damage states, detailed
Guide The role of abutments on the seismic vulnerability of bridges has been relatively little studied in geotechnical literature. To cover this gap, 3D
Guide During an earthquake the bridge movements are restrained by the high capacity wing walls and the backfill soil. The seismic performance of the new earthquake resistant abutment is
